范围1。1.1本标准第一部分和第二部分覆盖膏、半液体或液体型管接头密封化合物，用于密封具有NPT锥形螺纹的金属管道上的螺纹接头。1.1.2A至少应提交3个密封化合物容器，每个容器的重量不超过16盎司（0.45千克）。1.1.3本标准规定了产品在制造时必须具备的最低能力、特性和性能，以便被认为适合在天然和/或液化石油气中使用- 煤气管道系统。1.1.4复合材料或材料的工作温度范围应至少为32°F至125°F（0°C至51.5°C），适用于室内管道系统，且至少为-40°F至125°F（-40°C至51.5°C），适用于室内和室外使用。制造商可以指定并在这些范围之外的温度下进行测试。1.1.5复合材料或材料的工作压力应至少为125 psi（861.8 kPa）。制造商可指定并在更高压力下进行试验。 1.1.6本文规定的室温应视为73.4°F±3.6°F（23°C±2°C）。1.1.7符合本标准规定的密封剂和材料应视为具有制造商规定的工作温度范围和最大工作压力。1.1.8如果本标准中给出的测量值后跟其他单位的等效值，则本规范适用。1.1.9除非另有规定，否则本标准中提及的所有psi均应视为表压。

Scope1.1.1Part I and Part II of this standard cover paste, semi-liquid or liquid type pipe joint sealing compounds which are intended for sealing threaded joints on metal piping having NPT tapered threads.1.1.2A minimum of 3 containers of sealing compound, each not exceeding 16 oz (0.45 kg) in weight, shall be submitted.1.1.3This Standard sets forth the minimum capabilities, characteristics and properties which the product must possess at the time of manufacture in order to be considered suitable for use in natural and/or LP-gas piping systems.1.1.4Compounds or materials shall have an operating temperature range of at least 32°F to 125°F (0°C to 51.5°C) to be considered suitable for use in indoor piping systems, and at least -40°F to 125°F (-40°C to 51.5°C) to be considered suitable for indoor and outdoor use. A manufacturer may specify and be tested to temperatures outside of these ranges.1.1.5Compounds or materials shall have an operating pressure of at least 125 psi (861.8 kPa). A manufacturer may specify and be tested to higher pressures.1.1.6Room temperature, as specified herein, shall be considered as 73.4°F ± 3.6°F (23°C ± 2°C).1.1.7Sealing compounds and materials complying with the provisions of this standard shall be considered as having an operating temperature range and maximum operating pressure as specified by the manufacturer.1.1.8If a value for measurement as given in this standard is followed by an equivalent value in other units, the specification.1.1.9All references to psi throughout this standard are to be considered gage pressures unless otherwise specified.
